Figure I is a vertical sectional view of my invention showing theinterior construction by which the operating parts are manipulated.`Fig.2 is a front view of the head showing the oscillating plate removed.Fig. 3 is a perspective View of the oscillating plz te detached from themachine. Fig. 4 is an edge view of the same. Fig. 5 is a detail of4 aportion of the machine frame, showing a time recording dial or watchpositioned in the same.

In the construction of my invention I provide a bed plate 6 mounted inany desirable manner upon a table or machine frame. On the bed plate ismounted the head 7, which consists fof a vertical portion 8 and ahorizontal portion 9, the horizontal portion having an enlargement 10 inwhich is suitably guided the needle operating bar 11. In the horizontalportion 9 is located a shaft 12, which has bearing in the same at thepoints indicated by the numerals 13 and 14. This shaft is provided Witha sprocket wheel 15 over which the sprocket chain 1G operates. the saidchain extending.;r downwardly7 through the vertical portion 8 and arounda sprocket wheel 17 mounted on the driving shaft 18 located beneath thebed plate (3.

This shaft has bearing on the brackets 19 and 20 \and on said shaft nearthe bracket 2O is supported a gear wheel2l, which meshes with a gearpinion 22 mounted on a shaft. 23, supported in the bracket. 2O and thebracket This shaft in turn is provided.

with a bevel-gear by which Aan ordinary shuttle mechanism is operated.The shaft 18 is provided with a balance and drivewheel 33 over which thebelt is passed for placing the shaft in operation. On the horizontalmember 9 of the head is provided a pin 254 on which the ordinary spoolof thread is placed, the thread being passed from the spool through theeye 35 of the pivoted lever 36 and motion i's imparted to the lever 3Gby means of the cam 37 mounted on the shaft- 12, andby the oscillatory7movement of the lever the thread is unwound from the spool. The end ofthe shaft 12- is formed into a crank 38 and to the crank is attached aconnecting bar 39, which is attached to the upper end of the needle barll so as to impart vertical movement `to the needle bar and needle bythe operation of the shaft 12. -The projecting end of the crank 38 isprovided with a pin 40 so arranged as to project into the elongated slot41 ofthe oscillating plate 42 and by the movement of the crank 'theplate 42 is placed Iin oscillatory operation on its pivot 43, this plateacting 'as the face plate concealing the mechanism Ain the enlargement.The oscillatingv plate is preferably constructed of two membersconnected together and provided with eyes 44 and 45 through which thethread is passed. The thread is then passed downwardly through the loop46 at the bottom before entering the eye of the needle point. The threadin passing from the eye 35 of the lever 36 is guided through the loop 47attached to the top of the machine head and from thence the `thread is`Vpassed through the eye 44 of the plate up over the guide 48 located inthe apex of the plat/e down through the opening 45 and through the loop4G. By this construction the thread is readily guided to the needlepoint with little, if any friction, the oscillatory movement of theplate 42 producing a much more effective result than the ordinaryvertical reciprocating lever now used on the ordinary sewing machinesfor guiding the thread.

In Fig. 5 I show a watch 49 located in the vertical portion 8 of thehead 7,'Which -is for the convenience of the operator for timing thework.

Having fully described my invention what I claim is:

A sewing machine comprising a hollow head, a base plate supporting thesame, a horizontal shaft mounted in the hollow head, a horizontaldriving shaft supported beneath the base plate, a chain connecting bothshafts. a crank formed on the end of the shaft in the head, a cammounted on said shaft, a lever piroted to the head, its one en'dcommunicating with the cani, an oscillating plate covering the openingof the head and pivotally mountedat its bottom, In test-imony'whereof, Ihave signed my said oscillating plate having an elongated name to thisspecication, in presence of two 1o slot through which thel c rankprojects, said subscribing Witnesses. plate provided with eyes throughwhich the 5 thread is passed from the Spool on the head vand a loopformed at the bottom of the plate Witnesses; for guiding the thread to aneedle, sub- S FEINBERG Vstaotially as specified. l W ALTER Q STEIN.
